You can safely use the appliance on wet skin. For optimal performance, however, we advise you to use the appliance on dry skin.
If you want to trim wet, we advise you to use a small amount of your usual shower gel or foam for a gentler trim.
To get a good result, clean the trimming head with running water from time to time during use.
Also clean the appliance with running water after use and let all parts dry before you store them.
